APPARATUS FOR PROVING DOUGH PREPARATORY T0 BAKING.

Specification of Letters Patent;

'Patented June 1, 1915.

Original application filed July 1,3, 1909, Serial No. 507,307. Divided and this application led September 22,1913. seria1No.791,o5o.

To all 'whom it may concern f Y Be it known that I, GEOEGE SAMUEL BAKER, a subject of the King of England, residing at London, in England, have invented a certain new and useful Improvement in Apparatus for Proving Dough Preparatory to Baking, of which the following is a specification.`

This application is'a division of my application filed July l 13, 1909, Serial No.

507,307, for apparatus'for treating dough. l

This invention relates to apparatus for the treatment of dough preparatory to baking, and relates to apparatus concerned in\ the proving of said dough, that is 4to say the final proving operation between the molding thereof and its introduction into the oven.

For the purpose 0f this invention/'I may use a moldingapparatus of any `desired or approved construction and preferably adjacent to the discharge end or portion thereof I provide one or a series of endless-beltfor other conveyers on which are placed the known setting trays or boards on which the molded masses of dough either in tins or otherwise are placed in series or rows according to the capacity of said trays. The said conveyer carries the trays or boards or tins with a comparatively slow continuous or intermittent movement (during which time they are filled with loaves to be proved) toward the proving apparatus which comprises a series of endless chainscarrying suspended receptacles for reception of the trays, boards or tins, and when the end of the conveyer is reached suitable mechanism is brought'into operation whereby a rapid lateral movement at right angles to that of the conveyer is imparted to each tray in succession whereby it is transferred onto a receptacle of the proving apparatus.

The trays or tins containing the molded loaves are carried through the proving chamber in a circuitous course and as they arrive at the, discharge end of said chamber` they are transferred by means actingc similarly to the transfer of the trays to the prover above described to the front or inlet portion of the oven which -lattermay be ofthe type in which the material to be baked travels continuously therethrough or of the ordinary draw-plate or other desired construction. i

The invention is illustrated 1n the accompanying drawings in which- Figure 1 is a vertical elevation of one end of the apparatus showing the proving chamber and feed device. IFig. 2 is a sectional view of the opposite end of said apparatus showing the proving chamber and discharge device, and Figs. 3 and 4 are detail views of the feed and discharge devices respectively.

In the construction shown 50 designates the proving chamber which contains proving means proper of a substantially known type comprising chains carrying pivoted shelves or supports 61 for reception of the traysv or boards or the grouped and integral series of tins before referred to. Said chains pass alternately upward and downward about pulleys 62 and according to this form of the present invention are passed under the floor of the bakehouse or other chamber, as shown, extending at one side or end of the apparatus past the feeddevice 63 and at the other side or end past the delivery or discharge device 64 which latterconveys the trays or groups of tins directly to the oven 65'. y

71 designates a conveyer capable of movement at right angles to the movement of the chains and on which the trays or tins are placed by hand and filled while thereon.

The feed device more particularly shown in Fig. 3 and which may be used for either trays or grouped tins but shown as acting in conjunction with the latter comprises a slide or pushing member 66 adapted to be given rectilinear horizontal movement at the required times by means of the levers 67, rod 68 and interrupted gearing 69 whereby the group of tins 70 is pushed off the conveyer 71 directly onto the shelves or supports 61 of the proving chains 60. The gearing 69 is shown as driven from the shaft 72 which drives said chains 60, by means of chain and gchain wheels 73, shaft 74 and bevel gearing 7 5. w

Where grouped tins only-are being dealt with a similar mechanisml to that just described may be used to deliver same from the chains 60 to the oven 65 which in the form shown comprises a traveling endless sole 77. Where however trays or boards 78 with the tins thereon are used it is necessary Y .operated in a similar manner to slide 66 de- 4slide by the chains 60; the interrupted gearl `ing then -operates the levers 67 and moves the slide forward to position C whereupon the finger or plate 8'2 descends behind the,

tins 70 land remains in this position while the slide is moved back, thus stripping the tins ofi onto the oven sole 7 7. 4The slide moves back to position lA where the tray is removed and is then again moved forward to position B Where it is ready to receive the next tray.

What I claim .as my invention and desire to secure by Letters Patent of the United States is c* v 1. An apparatus for the final proving of dough preparatory` to baking which includes a proving chamber having inlet and outlet, a main endless conveyer positioned to travel through said chamber ina circuitous course and provided with suspended means for supporting dough receptacles; reciprocating means adjacent the inlet of the chamber for feeding the receptacles ont-o the supporting means of the main conveyer, and reciprocating means for discharging the receptacles from the supports of said main conveyer.

2.' An apparatus for the final proving of dough preparatory to baking which includes a proving chamber having inlet and outlet, a main endless conveyer` positioned to travel through said chamber in a circuitous course and provided with pivotally suspended and provided with suspended supports for 6o tively connected therewith, and means for discharging the receptacles from said supports,said means comprising a reciprocating slide and interrupted gearing operatively. connected therewith.

4. An apparatusfor the final proving of dough preparatory to baking which includes a proving chamber having inlet and outlet, a main endless conveyer positioned to travel through said chambervin a circuitous course and provided with suspended supports for 75 'dough receptacles, means adjacent the inlet of said chamber for feeding the receptacles onto said supports comprising a .reciprocat- Y ing slide and interrupted gearing' operatively connected therewith, and means for discharging the receptacles from saidsuppoi*tssaid means comprisi'n a slide reciprocatable in a direction at rig t angles to said conveyer, interrupted gearing 1n operative connection with said slide, and astopping finger adapted to remove the receptacles `from said slide during thev reciprocation thereof.

5. An apparatus for'the final proving of dough preparatory to baking which includes a proving chamber having in let and outlet, a main endless conveyer`positioned to travel through said chamber in a circuitous course means for supporting dough receptacles,

means adjacent the inlet of said chamber'foi" feeding said receptacles to the main conveyer comprising an endless feedingconveyer adapted for movement in a direction rectangular to said main Yconveyer, reciprocating means for transferring the receptacles from said feed ,conveyer onto` the supporting tacles from the supports of sai mainy conveyer. l,

3. An apparatus the v"final proving of dough preparatory to baking which includes f.

, A means of the main' conveyer, and recipro eating means adapted to dischar e the recepf and providedv withvpivotally suspended means for supporting dough receptacles,

means adj acentthe inlet of said chamber for feeding said receptacles to the main `conveyer comprising an fendlessfeeding conveyer adapted for movement 1n a direction rectangular to said main conveyer, means 100 l for transferring the receptaclesl from said feed conveyer onto the supporting means of the 'main conveyer, said means comprising a reciprocatingi slide and interruptedA gearing in, operative"" connection therewith, vmeans adaptel to discharge thel receptacles lfrom the supports of said .main conveyer,- said means comprising' a reciprocatiiigslide and interrupted gearing ,in operative connection therewit .I l, t

I witness whereof I have signed this spe ification in the presence i of two wit-1 nesses.
